To all whom it may concern.-

Be it known that I, CHARLES A. MAXFIELD, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Treating Textile Fabrics, Paper, &c., with Waterproofing, Coloring, or Glossing Substances, of which the following is a specifica- IO tion.

My present invention relates to apparatus for coating or saturating textile fabrics, paper, leather, and similar substances with wax, or with any desirable waterproofing, coloring, or glossing substance. It is adapted to the use of the natural wax known as ozocerite, paraffine, gums, india-rubber, and analogous strengthening, preserving, and waterproofing materials; and is also designed for use in applying coloring or glossing materials to the surface of paper and fabrics of various descriptions and grades.

My object is to produce an apparatus which is simple in construction and effective in 0peration, and one adapted to apply the waterproofing, strengthening, glossing, or coloring substance as a coating simply to the surface (one or both) of the material operated upon, or to completely saturate the said material.

My invention consists in the organization herein shown and described, and in certain details of construction. The subjectmatter for which I desire protection in this instance is pointed out in the claims at the end of this description.

In the accompanying drawings, which form a part of this description, and in which like letters indicate like features, Figure l illustrates a vertical central longitudinal section of a machine organized according to my invention. Fig. 2 is a plan View of the same machine. Fig. 3 is a crossseetion through the line y y, Fig. 1. Fig. 4 is a cross-section througlrthe line a: :0, Fig. 1. Fig. 5 is an enlarged detached view of the plate E shown in Fig. 3, which forms a part of the wax-receptacle hereinafter described. Fig. 6 is an enlarged view of the elements forming the receptacle, said view being a longitudinal vertical section showing one of the side plates in elevation. Fig. 7 is a plan view of one of the side plates; and Fig. 8 is a detail view of a brake mechanism, shown attached in Fig. 2

to the shaft of the paper-delivery reel.

Referring to the drawings, A indicates a 5 5 .frame, which may be of cast-iron or of any vided with shafts B and C,respecti.vely,which have bearings in the frame of the machine in the usual manner. The upper longitudinal bars, a, of the frame A support the castings, which constitute the receptacle and the distributer.

The receptacle, as shown, is composed of two iron castings, D D E, forming the front and rear walls, and that wall D of said receptacle nearer the delivery-reel is so shaped on its under side as to provide a smooth surface for the paper to travel under and insure close contact between paper and casting while the paper is passing under the receptacle, as shown. The inner surface of the casting D is vertical and smooth, except near its lower end, where it is provided with a projection constructed to form one element of a dovetail s connection. A pipe, d, is located within this casting D, as shown, and at the top of said casting is a flat piece of metal, d of the requisite length, secured rigidly thereto, and provided with screw-bolts, whereby the said 8 casting D may be adjusted longitudinally of the frame in order to increase or diminish the distance between the castings D and D E. The casting D is similarly constructed, except that it has no projection on its in 9Q ner face, as is the case with the casting D. It is preferably curved on its outer surface and flat on-'its under surface, and it has secured to its inner wall, by set-screws e, the blade E, or this blade may be cast as part of it. The holes to receive these set-screws e are The blade E may project upward above the frame of the machine. The casting D is also provided with a pipe, d, and with the flat piece of metal d at its top, having setscrews which permit the adjustment of said casting lengthwise of the machine, in order to bring it nearer to or farther from the casting D.

F represents the two-part side plates,which are shown enlarged in Figs. 6 and 7. These plates overlap each other and are adjustable in length by means of the set-screw f. The outer end ofeach of these plates is provided with a slot formed so as to receive the projection on the inner wall of the casting D and blade E, respectively, thereby completing the dovetail joint between the respective castings and the side plates. There are two sets of the plates F, one at each end of the receptacle, and they are of sufficient height to form the end walls of said receptacle, and while their upper edges are straight their lower edges incline 'slightly from the casting D to the beveled edge of the blade E, so as to insure an easy movement of the paper beneath the receptacle. The blade E, forming the rear wall, may be made without the casting D, and heated in another manner.

Immediately above the receptacle is atank, G,which is supplied with the coating or saturating material, liquefied and kept hot by any suitable means. At the bottom of this tank is a series of discharge-cocks, 9, having projections from their plugs connecting with a rod, 9, whereby all the cocks may be opened at the same time and in the same degree, and thus insure the supply of the liquid to the receptacle evenly over the surface of so much of the material operated upon as for the moment forms the bottom of this receptacle.

From this. description it is plain that my receptacle has no bottom; that its front and rear walls are formed by the castings D and D E, which may be adjusted toward or from each other, so as to increase or decrease the space between said walls; that its side walls are formed by the two sets of side plates, F, which are detachably connected to the castings D D E, and which may be adjusted in length by the set-screws shown, so as to accommodate themselves to the adjustments of the castings D D E. The side plates are also adapted to be moved transverse of the machine toward or from each other, in order to increase or diminish the width of the receptacle according to width of the paper or fabric operated upon. Thelongitudinal adjustment of the receptacle is for the purpose of increas ing or diminishing the surface of the liquefied substance in contact with the material operated upon.

Projecting from the edges of the plates F are lugs f, which receive set-screws f so that when the plates F are properly adjusted they may be locked in position.

H represents a pivoted bar secured upon the frame of the machine by a central pivot and extending transverse of the frame. This bar is located just in advance of the deliveryreel B, and is adapted to hold the paper above the lower surface of the casting D, so as to insure proper contact between the paper and the lower surface of said casting. The fact that the bar H is pivoted also insures the passage of the paper beneath the receptacle in an unru'ffled manner, as any irregularities in the paper are compensated for by the automatic adjustment of said bar.

At a suitable position on the frame is secured the casting I, which is constructed the same as casting D, having an interior pipe, at,

and flat and curved walls. To the flat face of this casting is secured in a detachable and adjustable manner the blade J, whose lower end is beveled. The casting I is adjustable longitudinally of the machine by the set-screws passing through the plate at its top. The function of blade J is to further insure the even distribution of the material upon the paper or fabric operated upon.

Between the castings D and I is arranged the bar K, pivoted to the frame and capable of being thrown in and out of operation when desired. The function of this bar K is to keep the paper properly in contact with the blades E and J. v

The tension on the delivery-reel B is regulated by the device shown in Fig. 8. The application of this device to the shaft of the delivery-reel is shown in Fig. 2. This tension device consists of a metal strap, K, secured at land passed over the shaft B, the free end of the strap being connected to the spring m, which spring is connected with abar, n, the latter being secured near the base of the machine and provided with means for depressing or elevating it, so as to increase or decrease the strain on the spring, and thereby easily regulate the tension of the deliveryreel. The pipes d forming parts of the castings D, D, and I, are connected by means of suitable couplings with steam-supply pipes L. Hot air or hot water may be used instead of steam for heating the castings forming the receptacle and the casting I, and, for convenience, the pipe of casting D may be connected permanently with the pipe of casting I, in which case the longitudinal adjustment of these two castings will notbe independent of each other, and the relative distance between the castings of the receptacle will be regulated by the longitudinal adjustment of the casting D.

In operation the paper or other material to be treated is conducted from the delivery-reel B over the pivoted bar H, under the bottom of the casting D, and beneath theopen bottom of the receptacle and blade E, from which point it is carried over the pivoted bar K, under the blade J of casting I, to the receiving-reel G.

In this position the paper or material to be of the liquefied substance is of course to be regulated according to the quality of paper or other material operated upon, and according as to whether the paper is to be saturated or merely coated. In operating with very thin paper but a small depth of liquid would be allowed to pass into the receptacle, and this would be the praeticein operating upon heavy paper where the object is to coat and not saturate. If the liquid is to be struck through the paper so as to saturate it, a heavier body of liquid would be allowed to enter the receptacle D D E. The liquid in the receptacle D D E is kept at a predetermined temperature by regulating the degree of heat permitted to affect the castings forming the walls of said receptacle.

The revolution of the reel 0 draws the paper M from. the reel B over the equalizing pivoted tension-bar H, under the wax-receptacle, and under the blade J, after passing which latter point it is sufficiently treated to be wound upon the receiving-reel O.

The blade E prevents any undue quantity of the liquefied material from adhering to the paper or other material being treated, and such as remains upon the paper or other material treated is further equalized upon its surface during the act of passing under the lade J.

In practice I may dispense with the front wall, D, of the receptacle, leaving this recep tacle to be formed-of the rear wall, D E, and attached side walls, F, with the incline of the material operated upon, the walls F being made with an incline to conform.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus of the character herein described, a receptacle for the liquefied sub stance to be applied to the material operated upon, consisting of front and rear walls secured to the frame of the apparatus and provided with adjustable side walls, said structure being open at the bottom, so that the material to be operated upon, when passing beneath the same, is in direct contact with the liquid, substantially as set forth.
